摘要

The present invention relates to a method for repairing and reinforcing a sink part of a cleaning equipment that is used to clean a semiconductor, LED and LCD. To this end, the present invention comprises; the first reinforcement step(S100) of cleaning the sink part of the cleaning equipment and reinforcing the leakage regions; the second reinforcement step(S200) of forming the lower reinforcing layer with SHT-715(SHT-715A as a subject and SHT-715B as acuring agent) on the bottom surface of the sink part; the third reinforcement step(S300) of forming the middle reinforcing layer with SHT-146(UV Filler Coat) on the upper part of the lower reinforcing layer and sidewalls of the sink part; and the fourth reinforcement step(S400) of forming the upper reinforcing layer with SHT-1500(UV Coat) on the surface of the middle reinforcing layer.
